What Does A Safety Nut Do?

A Safety Nut Provides 2 Safety Roles:

1) In the event of excessive wear on the nut thread the load will be transferred from the standard nut to the safety nut. This will also provide visual wear indication as the gap between the safety nutdecreases to zero as the standard lifting nut wears.


2) In the unlikely event of catastrophic nut thread failure the safety nut will sustain the load.

Should the screw thread on the lifting nut or gear fail or wear out then the safety nut will support the load. The safety of industrial and human cargo is therefore improved.


Visual Wear Indication 

The safety nut can be used to monitor the wear on the lifting screw threads on the lifting nut (rotating screw jack) or worm gear (translating screw jack). As the lifting screw thread on the nut / gear wears the gap between the safety nut and the nut / gear reduces to zero. This allows for wear monitoring and scheduling of preventative maintenance before parts become worn out.
